Scientific objectives and approach:
The initial work will focus on the development of the TSAO laboratory research reactor to be used in the subsequent development of the analytical technologies for the individual contaminant species. Analysis will be based on the proven TOC analysis with innovative colour chemistry for nitrogen, phosphorus and metal ions. The reactor will incorporate the necessary flexibility to enable the different reagents and colour indicators to be introduced.
Spectroscopic studies for the oxides of each element will be carried out with the aim of using diode arrays to measure the oxide concentrations. This will enable the prototype optical bench to be incorporated into the reactor system while minimising interference effects and eliminating the potential for contamination of the developed optical system.
Sub-system designs for optical diode arrays and emitters, pumps, mass flow controllers, ozone generators, control and display software will be integrated into the multi-component pollution analyser for continuous on-line industrial use. This will be validated at a range of end user sites and the technology transferred to all partners in preparation for exploitation.
Problems to be solved:
The aim of the project is to develop an innovative analytical technology involving a patented two-stage advanced oxidation (TSAO) process that ensures complete reaction and hence measurement of a whole un-filtered sample. This unique oxidation technique has the potential to continuously operate on-line, and in real "dirty" effluent. Feasibility studies have demonstrated this can be expanded from the measurement of organic carbon pollution and be applicable to the monitoring of total nitrogen, phosphorus, and heavy metals, e.g. aluminium and copper. However, this potential to out perform current techniques needs to be developed and proved in terms of accuracy, durability, portability, and cost, to enable significant market opportunities to be realised.
This proposed project will contribute to the implementation of EU policies such as the EU Water Framework Directive and European Integrated Pollution Prevention and Control Directive. This will be achieved through direct contribution to improving the quality of life, the health of the population, and pollution prevention by the development of a rugged, reliable, and accurate continuous on-line equipment for water quality monitoring.
